I assume this isn't all of the cars, as I can see a bunch more from screenshots on Google.

From what I can see, there's also a prototype car that I'm not sure if it's a Porsche, Mazda, or Toyota, a Pagani Zonda, a McLaren MP4-12C, an Aston Martin Vantage, an LMP that might be an R18 or a TS040, a Ford GT40, Shelby GT500, Formula 1 car, Bugatti Veyron...
